  • M/T Ole Jacob NS *
Johs. Hansen, Arendal
8306 gt
Built in Gothenburg 1939.

Captein Leif Christian Krogh. On a voyage from Singapore to Suez with a cargo of 10 000 tons aviation fuel when she was captured by the German auxiliary cruiser Atlantis on Nov. 10-1940, position 06 30N 90 13E. Please go to my page Norwegian Victims of Atlantis for a lot more details on this incident, including crew list, excerpts from the maritime hearings, and her subsequent history and fate, as well as information on all the other Norwegian ships captured by this raider.

Her voyages prior to capture are listed on this original document received from the National Archives of Norway.

NOTE: Norwegian sources state that the crew from Ole Jacob (and M/T Teddy, captured by the same raider) were freed through diplomatic avenues (again, there's more details on the page mentioned above). However, I've been contacted by an Australian man who says his Norwegian father, who was on board Ole Jacob, was definitely not freed, but ended up in Japanese camps. His message can be found in my Guestbook. If anyone can shed some light on what happened to the crews of Teddy and Ole Jacob, please contact me (my contact address is at the end of this page).
